This book was released on 2006 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains background documents and papers presented at a workshop on integrated irrigation aquaculture (IIA), held in Mali in November 2003, as well as the findings of FAO expert missions on IIA in the West Africa region. The rationale for IIA development lies in its potential to increase productivity of scarce freshwater resources and to reduce pressure on natural resources, issues of particular important in the drought-prone countries of West Africa.
Download or read book Ecological Aquaculture written by Barry A. Costa-Pierce and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world's demand for food from aquatic environments continues to increase, the importance of performing aquaculture in an environmentally responsible manner also increases. The aim of this important and thought-provoking book is to stimulate discussion among aquaculture's modern scientific, education and extension communities concerning the principles, practices and policies needed to develop ecologically and socially sustainable aquaculture systems worldwide. Ecological Aquaculture provides fascinating and valuable insights into primitive (and often sustainable) culture systems, and ties these to modern large-scale aquaculture systems. The book is edited, and authored to a considerable degree, by Barry Costa-Pierce who has assembled a team of some of the leading thinkers in the field, providing information spanning a spectrum of activities from artisanal to high technology approaches to producing aquatic organisms in a balanced and environmentally-friendly way. Ecological Aquaculture is an essential purchase for all aquaculture personnel involved in commercial, practical and research capacities. Libraries in research establishments and universities where aquaculture, biological, environmental and aquatic sciences are studied and taught should have copies of this book available on their shelves.

This book was released on 1998 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: "(Reprint. First published in 1998) The present study is an update of an earlier assessment of warm-water fish farming potential in Africa, by Kapetsky (1994). The objective of this study was to assess locations and areal expanses that have potential for warm-water and temperate-water fish farming in continental Africa. The study was based on previous estimates for Africa by the above author, and on estimates of potential for warm-water and temperate-water fish farming in Latin America by Kapetsky and Nath (1997). However, a number of refinements have been made. The most important refinement was that new data allowed a sevenfold increase in resolution over that used in the previous Africa study, and a twofold increase over that of Latin America (i.e. to 3 arc minutes, equivalent to 5 km x 5 km grids at the equator), making the present results more usable in order to assess fish farming potential at the national level. A geographical information system (GIS) was used to evaluate each grid cell on the basis of several land-quality factors important for fish-farm development and operation regardless of the fish species used. Protected areas, large inland water bodies and major cities were identified as constraint areas, and were excluded from any fish farming development altogether. Small-scale fish farming potential was assessed on the basis of four factors: water requirement from ponds due to evaporation and seepage, soil and terrain suitability for pond construction based on a variety of soil attributes and slopes, availability of livestock wastes and agricultural by-products as feed inputs based on manure and crop potential, and farm-gate sales as a function of population density. For commercial farming, an urban market potential criterion was added based on population size of urban centres and travel time proximity. Both small-scale and commercial models were developed by weighting the above factors using a multi-criteria decision-making procedure. A bioenergetics model was incorporated into the GIS to predict, for the first time, fish yields across Africa. A gridded water temperature data set was used as input to a bioenergetics model to predict number of crops per year for the following three species: Nile tilapia (Oreochromis niloticus), African catfish (Clarias gariepinus) and Common carp (Cyprinus carpio). Similar analytical approaches to those by Kapetsky and Nath (1997) were followed in the yield estimation. However, different specifications were used for small-scale and commercial farming scenarios in order to reflect the types of culture practices found in Africa. Moreover, the fish growth simulation model, documented in Kapetsky and Nath (1997), was refined to enable consideration of feed quality and high fish biomass in ponds. The small-scale and commercial models derived from the land-quality evaluation were combined with the yield potential of each grid cell for each of the three fish species to show the coincidence of each land-quality suitability class with a range of yield potentials. Finally, the land quality-fish yield potential combinations were put together to show where the fish farming potential coincided for the three fish species."

Download or read book Agroecological Innovations written by Norman Thomas Uphoff and published by Earthscan. This book was released on 2013 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's food supply needs to rise significantly, yet both arable and water supplies per capita are decreasing. Not only are modern agricultural methods beyond the reach of those suffering the greatest food insecurity but they are also ecologically damaging, relying upon fossil energy and chemical inputs. This volume offers a collection of innovative and diverse approaches to agricultural development.; Documented in 12 case studies, these approaches are reliant upon greater knowledge, skill and labour input, rather than larger capital expenditure. They are shown to increase yield substantially, sometimes doubling or tripling output. This volume presents the concepts and operational means for reorienting agricultural efforts towards these more environmentally friendly and socially desirable approaches in the developed as well as developing world.

Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture and the Environment Second Edition T. V. R. Pillay The continuing rapid increases in aquaculture production world-wide raise fears of further environmental degradation of the aquatic environment. The second edition of this well-received book brings together and discusses the available information on all major environmental aspects of various aquaculture systems, providing a valuable aid to the preparation of environmental impact assessments of aquaculture projects and showing how potential environmental problems can be reduced or mitigated by sound management. Much new information is presented in this new edition, including details of the impact of genetically modified food products and a new chapter on the sustainability of aquaculture, which covers the definitions of sustainability and responsible aquaculture, environmental, economic, social and ethical aspects of sustainability and the concept of ecotechnology in fish farming. Aquaculture and the Environment, Second Edition is essential reading for all personnel working on fish farms and for those moving into the aquatic farm business. Environmental scientists, ecologists, conservationists, fish and shellfish biologist and all those involved in the preservation of aquatic environments will find much of great use and interest within the covers of this book. Libraries in all universities and research establishments where these subjects are studied and taught should have copies of this excellent and useful book on their shelves. Dr T. V. R. Pillay was formerly Programme Director, Aquaculture Development and Coordination Programme, Food and Agriculture Organization of the United Nations.
